Loged in "Menu" changes

I am wondering if there is a way to change the displayed items in a menu when someone logs in. For example, the "Help" "Login" and "Sign Up" buttons on this site changing to "Help" "My Account" "Sign Up".

Thank you.

I think that the only way is creating additional menu and create an condition using http://codex.wordpress.org/Function_Ref ... _logged_in to load normal menu or the logged user menu.

I'll give it a try.
